WIRE-CUTTER."

To all whom it may concern:

Be it known that I, BRONISLAW Sonoeiu- SKY, a citizen of Russia.residing at Cosmopolis, in the county of Grays Harbor and State oflVashington, have invented certain new and useful linprmements in Nire-Cutters, of which the following is a specification.

The primary object of the invention is the provision of a wire cutterprovided in connection with a spear or knife whereby wires may bereadily severed permitting a person to pass through an obstructionformed by the wires and often arranged as a barbed wire entanglement.

A further object ot the invention is the provision of a wire cutter thatis light in weight and can be provided upon any suitable article withouttaking up any appreciable amount of room the same also serving as amount for bayonet or blade when desired.

A still further object of the invention is the provision of a wirecutter adapted for operationin actively cutting wires without requiringthe manual operation of pivoted,

members as required with the usual pair of shears, the cutting operationbeing accomplished by forcibly engaging a portion of the device againstan article to be cut..

Inthe. drawr Figure 1' is a side elevation of the device mounted upon abayonet;

Fig. 2. is a similar view thereof with the top plate and other elementsremoved, a wire being indicated by dotted lines in its cutting position;

Fig. 3 is a view similar to Fig. 1 with the cover plate broken away andthe device illustrated in its operative cutting position;

Fig. 4; is a plan view of the device; Fig. 5 is a sectional view takenupon line VV of Fig. 1;

F ig. 6 is a transverse sectional view thereof taken -upon line VlVI ofFig. 1,

with a wire illustrated in its operative position;

Fig. 7 is a perspective view of the cutting plate removed; Fig. 8 is aperspective view of the cover plate detached; and

Fig. 9 is a perspective view of the operating cam and lever detachedfrom the de vice.

My device for cutting wires may be readily mounted upon a sword, gun orsimilar 1m- Specification of Letters Patent.

plement and is herein illustrated mounted upon a bayonet or blade'lOhaving a shank or handle 11. A finger 12 is provided upon' to one faceof the bayonet 10 by means of screws 16 passing through the plate 15 andthrough a similar plate 1.7 upon the opposite side of the bayonet 10 andwhereby the device is fixed to the said bayonet.

The base plate 15 is provided with a rectangular cutting blade 18slidably mounted in a transverse dove-tailed groove 19 for movementtoward and away from the finger 12. The inner edge 20 of sald finger is.preferably sharpened to cooperate with the ad' jacent edge 21 of theblade 18 for shearing a wire 14 when positioned within the slot 13 inthe path of movement of said blade 18.

A cam 22 is pivoted within an opening 23 of the blade 18 by means of a.post 24, the said opening being substantially rectangle lar with arounded corner 25 so that upon revolving the cam 22 from the positionshown in Fig. 2 to that shown in Fig. 3, the toe, 26 of the cam 22 willengage one sideof the opening 23 for operatively shifting the blade 18.A coverplate 27 is mounted upon the base. plate 15 by theaforementionedscrews 16 with the post 24 outwardly extending through aperforation 28 in said cover plate. An angular operating lever 29 is journaled adjacent the upper end of the post Baby means of its shorterarm 30, which arm is connected by a staple 31 with the cam 22. Thestaple 31 is freelypositioned for n'iovement through a curved slot 32 inthe cover plate 27, while the other longer arm 33 of the lever 29,projects across the wire receiving slot 13 and beneath a U-shaped guide34 provided adj acent the outer edge of the finger 12. r

A spring 35 is positioned between the lever arm 33 and a lug 36 carriedadjacent the base of the finger 12 for normally holding the lever 29with the blade 1.8 retracted. During the operation of the device, theshank 11 being grasped by the soldier the wire 14 is forced inwardly ofthe slot 13 against the lever arm 33 which swings upon the pivot post 24shifting-the blade 18 toward the finger l2 and shearing the wire 14between the cutting edges 20 and 21. After the wire I has been severed,the spring 35 returns the I 'slot.

. of the blade and adapted for shifting. the' the curved side 38 of theblade I groove 19'by the hand ofthe' operator if deend .of the post 24and groove therein,

mg a cuttm lever 29' to its normal position ,andby placing'the curvedface-37 the blade opening 23, the blade is also retracted to its normalposition as. shown in Figs. 1 and 2 of the drawings,

18 may be retracted within the sired. A guard 39 is provided upon thecover plate 27 for receiving the outer headed V overlying the pivotedend ofthe lever 29. A strong and compact device is provided adapted forreadily cut ting wires upon a forward thrustimparted to the shank 11 bythe soldier in charge of the device. 1

What I claim as'new is -1. A wire cutter comprising a shank, a

base plate carried by the shank having a groove thereima finger upon theshank havmg a cutting-edge spaced from said plate forming a wirereceiving slot therebetween, a blade slidably mounted in said groovehaving "an opening therein, an operating cam for said bladepivotedwithin the openi-ng of the-blade and adapted for shifting the,blade toward said finger upon the rotationof the cam in one directom-andran lever for the cam projecting trans operating versely of saidslot adapteddor engagement by a wire'position for cutting within said 2.A, wire cutter rcomprising a shank, a base plate carried by a bladeslidably mounted in said groove having an opening therein, an operating.cam for said vblade pivoted within the opening blade toward said fingerupon the rotation of the cam in one direction, a cover plate upon saidbase and cam, an angular lever havingone arm pivoted above said coverplate, a staple connecting the said lever and (3am movable through aslot provided in said cover late, a'guide upon said finger overlying theever, and a return spring for the lever.

' 3. A device of the class described comprising in combination withashank', a bayonet projecting therefrom, a base plate and a rear platesecured together and positioned upon opposite sides of the bayonet, atransverse dovetailed slot through said base plate, a

I cutting blade slidably mounted in said slot of the cam 22 againstalthough it will be apparent thatv the shank having a a finger uponthe'shank havedge spaced fromjsaid plateformingj a wire receiving slottherebetween,

plate "overlying ,said blade with a curved slot above'said opening, afinger carried by said shank spaced from said base plate forming areceiving slot there between and having an inner cutting edge,

a pivot post extending through said cover the said wire receiving slotadapted for engagement with a wire during the operatlon of the d'evlce,

cam and extending throughsaid curved slot overlying; said lever andthereturn spring for the lever.

4. In combination with a mounting memher, a finger, having a cuttingedge therefrom, a base, plate upon said mounting member having a guidewithin said slot shiftable towardandaway a staple carried by said spacedslot therein,.a blade from the said finger and having a cam openingtherein, a cover plate upon said base plate overlying the opening andhaving a curved slot opening adjacent the said finger, a campivotally-mounted in said opening be cam pivoted above the cover plateand conofthelatter, the said lever projecting across theopening ingmember adapted upon engagement with a wire to shift said blade towardsaid finger whereby the wire-is severed by engagement with said bladeand finger. 5. In combination with a mounting member, a'finger having acutting edge spaced therefrom,a -base;plate."upon said mounting memberhaving a guide slot therein, a blade within said slot shifta'ble towardand away from the said finger and having a cam. opening therein, a coverplate 'upon said base plate overlying theopening and having abetween thefinger and mounttween said plates, an operating lever forthe curved slotopening adjacent the said finger,
